<p>The system has a clamp (4) clamping two friction elements (2, 3) on two sides of a rotary braking element (1), where the friction elements are moved between two extreme positions. A guiding unit (5) guides the movement of the two friction elements on the clamp. A control unit (6) controls the displacement of the two friction elements between an extreme rest position and a braking position. The control unit is attached to an actuator i.e. linear actuator, that comprises a drive train (8) for controlling the friction elements.</p> |
